Yes SE's were optioned with the L36. Since you do have the 3.8 then do what was recommended with the insert, o-rings etc.

Yep.

Thanks I will definatly do that hv3 insert whatever that is, is it something I have to order or does it come with gaskit kit(s). I know when I ask for a kit they ask me if engine has the (something]/with line up pins or not, (don't know}. I just tell them I will buy both sets and return the other.
Sorry having a fewer then few beers right now and don't remember exactly what was asked from autopart stores.

is the link to the HV3. The Butt Dyno shows noticeable gains, the ears say there's a difference, and the fuel efficiency math tells of better flow. Couple that with a CAI, and you should be a happy camper.

The gasket kit I bought was from the dealership. Expensive, but I was sure that it was the updated gasket version.

not the greatest of write-ups, but the pics start on this page, follow the link:

The HV3 is a flat piece of plastic, the UIM insert is flawed, at best. Now's as good a time as any to get a pic posted up. I'll do that today.

I have a thread on here of an hv3 install in my SE.

Thanks for the info guys, would this be recomended for the automatic, or more for the manual tranny's, mine's a automatic.

The w-bodys are automatic unless ur brave and do some custom work.

..also couple that with a downpipe/powerlog and you will see even greater gains.

Or don't waste your time with a dp/powerlog and get a used set of headers and see even bigger gains.

You all are great thanks for the help and tips,
There's a few gp's in the jy's around hear I am sure I can find some good used headers. but I will keep my ears/eyes open for any on sale/for sale on here, be a while before I can get them, though, got to get this engine together first, attacking it little at a time, here and there.

I doubt you're going to find any headers on a junkyard car. No one mods these things, so there is a very small chance to find them out of the blue.

only consider plogs if you going turbo.

Have you had a plog or headers? Plogs are nice especially for the people who don't want the task of installing headers
